Title: Hello Brightboxers

I've added a nice parameter verifier - and it makes sense to me to add it to Rujistsu, as it's a bits-and-bobs collection of helper routines.

Basically if your method takes a Hash, you can then specify which keys (or values) it should contain and it will raise an ArgumentError for you.
